Sorry. I was not clear enough in my description. Made assumptions. 
I meant the "Floor" you added to your scene and converted to terrain.

Initially I tried adding the persona (Mason) to my character but the perform actions (walk and think, walk bump into object) are the only two walking actions.  The Walk think option sends the character out of the screen frame and the walk bump into object action is just strange.

Even though it makes the character walk, that is actually a "Perform" command. There used to be Personas that included both a "Perform" and "Move" in the r-click menu. The current ones only have "Perform".

The "move" worked in a much different way. If you imagine the character in a box, and move that box while the character animates in place inside it, that is what the "Move" command did. That is usually how a character works in games.

If you would like to try one that has "Move" commands, you may download this custom one that I made.

It is comprised of two parts. The Persona file, which you can store in any folder you like, and a folder full of iMotions. Put that folder full of iMotions  into your Template motion folder. C:\Users\Public\Documents\Reallusion\Template\iClone 7 Template\iClone Template\Motion

When you load the Persona, it will have a "Move" in the r-click menu. Selecting "Move" will present you with several options in a fly-out sub-menu. There are also a couple "Perform" motions included.

Thank you - I appreciate the aml and the motions.
Looks like if I am going to accomplish what I need to do I will need to figure out how to write / edit persona's and motions!

That clarifies it.  I can now have my character walk on the porch..
All of your help is really appreciated.

Glad it worked!
You can take it a step further by creating a path that you want the character to follow. to do so right click and select a move command for your character, and then click on any path in your scene. The character will walk to the near end of the path and then along it. Note that you do not attach the character to the path to do this. So you can walk easily from one path to another.

Sorry I confused things by misunderstanding your issue. I had a very similar issue working with custom personas I created in 3dx 7, but it's a different problem, though it results in the same kind of glitch. I'm glad Rampa was able to set things straight.

Thanks again.
Now I'll be posting another question dealing with vehicle motions

Hi everyone, hope I'm at the right forum for this!! Ive just read some of the posts here and I wonder if I could explainmy issue? In iclone 7 I have a road set, created in sketchup and a bike model also created in sketchup. Both props added to my scene. I want the bike to move over the curves in the road so I selected follow terrain from the edit menu but the bike just moves through it. So I created a path and then chose snap to terrain. But it snapped to a straight line above the curves below. Is this rectified by using the self mesh option or am I stuck with the bounding box rectangle surrounding my road prop? Any help would be great here as I can't move on to my next scene. I could key frame the bike but that's a ton of work and I' know there must be a way to get it to snap to the set prop. Thanks. Jim

It is a bug yet to be addressed by RL https://www.reallusion.com/FeedBackTracker/Issue/Follow-Terrain-and-Projected-Path-Inconsistensy
Here is one way to handle it at the moment:
